The SBE 41/41CP uses the proven MicroCAT Temperature, Conductivity, and Pressure sensors. The CTD is shipped fully calibrated, and has demonstrated excellent long-term stability, eliminating the need for post-deployment tampering of the calibration to force agreement with the local TS.
Designed for long term deployments
The SBE 41/41CP has carefully engineered anti-foul protection, with anti-foulant devices, a U-shaped flow path, and a pump.
The SBE 41/41CP has proven TC-Ducted flow over the temperature sensor and into the conductivity sensor. Salinity spiking is minimized because the TC-Duct and pump precisely coordinate the T and C responses.
Standard Float CTD
Satisfies 90% of the annual Argo program requirement as well as a growing market in non-Argo float applications.
Conductivity Accuracy:± 0.0003 S/m (± 0.0035 psu)
Conductivity Typical Stability:0.0003 S/m/month (0.0011 psu per year)
